Prerequisites for hadoop windows

This tutorial has been written for and tested with Hadoop version 0.19.1. If you are using another version, some things may not work.Make sure you have exactly the same versions of the software as shown above. Hadoop will not work with versions of Java earlier than 1.6 and versions of Eclipse later than 3.3.2 due to plug-in API incompatibility.

Installing Cygwin

After installing the prerequisite software, the next step is to install the Cygwinenvironment. Cygwin is a set of Unix packages ported to Microsoft Windows. It is needed to run the scripts supplied with Hadoop because they are all written for the Unix platform.

Run the downloaded file. You will see the window shown on the screenshots below.
